Title: Pyridine-4-carbothionic acid derivatives
IPC: C07D213/86
Filed: 1954-07-05
Abstract: A process for making pyridine 4-carbothionic acid hydrazide and hydrazones thereof comprises halogenating 4-methyl-pyridine by treatment with halogen while in solution in a substantially inert diluent medium and in the presence of an agent capable of substantially neutralizing hydrogen halide, under conditions favouring side-chain substitution to yield 4-trihalogenomethyl-pyridine, reacting this product with an inorganic sulphide wherein the cation is an alkali metal, alkaline earth metal or a nitrogenous base while in solution in a polar organic solvent, whereby the cation salt of pyridine-4-carbodithionic acid is obtained, and reacting this product with hydrazine or a hydrazine salt in an aqueous reaction medium, whereby the pyridine - 4 - carbothionic acid hydrazide is obtained, and optionally reacting this compound with an aldehyde or ketone to convert it into the corresponding hydrazone.  The reaction with the sulphide is preferably effected in an inert atmosphere at a temperature up to 60 DEG  C.  In Example (1) 4-methylpyridine is chlorinated in acetic acid in the presence of sodium acetate, and the 4-trichloromethylpyridine obtained is treated in an inert atmosphere with a mixed solution of potassium in methanol, of which half has been saturated with hydrogen sulphide giving the potassium salt of pyridine-4-carbothionic acid reaction of which with hydrazine hydrate in the presence of potassium carbonate gives pyridine-4-carbothionic acid hydrazide. In further examples the product of Example (1) is reacted with (2) salicylaldehyde; (3) pyruvic acid; (4) 4-acetamidobenzaldehyde; and (5) p-benzoquinone to give the corresponding hydrazones of pyridine-carbothionic acid hydrazide.

Title: Valve structure for the control of fluids
IPC: F15C3/14
Filed: 1956-06-26
Abstract: 820,573. Fluid-pressure servomotor control systems; fluids; regulating volume of flow; valves. BOEING AIRPLANE CO. June 26, 1956 [July 22, 1955], No. 19787/56. Class 135. A valve comprising a body having a main circular cross-section bore, a smaller bore intersecting the main bore to define at least one port, a loosely fitting closure member controlling the port, a stem rigid with the closure member and with mounting means closely fitting the bore and flexible means interposed between the valve body and the mounting means for laterally deflecting the stem and closure member on application of a lateral force adjacent the mounting means to control the port opening. As shown in Fig. 1, the valve body 1 has a circular, parallel bore 10, diametrically opposite transverse ports 11a, 11b opening into the bore and an extension 14 formed with an annular groove or neck 13 adjacent the body. Within the bore a rigid stem carries at one end a circularsection closure head 4 normally centrally disposed and having a clearance of the order of 0.001 inch to 0.003 inch with the bore and at its other end a mounting member 41 fitting and closing the bore and connected to an actuator 42. On application of a force F to the actuator on, e.g., variation in a mechanical or electrical imput signal, the extension 14 flexes about the neck 13 so that the opening of one of the ports 11a, 11b is reduced and of the other is increased to provide a pressure differential which may be used to control a servomotor. In modifications, the closure head may be conical and the bore opposite the ports similarly coned or the head may be spherical to ensure full closure of either of the ports 11a or 11b. In another modification, a groove 15, Fig. 5, in the body provides a flange 1a through which screws 15a pass to enable the closure head 4 to be initially adjusted in its central position. In another arrangement, a tube 16, Fig. 7, is a close fit in a sleeve 17 which is sealingly and resiliently mounted in the body 1. Grubscrews 15e adjust the sleeve and tube so that the head 4 is initially centralized whilst notches 13a in the tube provide the flexibility to control movement of the head 4. When used as a flow restrictor, a spherical head 4b, Fig. 12, mounted on a stem 40 coacts with the ported tube 16. A groove 13b provides the flexibility and grub-screws 15c allow of initial adjustment. More than one pair of oppositely disposed ports may be fitted and a force F 1 , Fig. 14, will be resolved into components F 2 , F 3  in the planes of the ports to simultaneously control two servoamplifiers.

The loop is passed beneath the floating layer 12 and then upwardly through it to collect the material onto its surface. The collector loop is driven by a first wheel 17 having teeth 21a, 21b which grip the loop 16 and pull it upwardly out of the liquid over a second wheel 15 which does not grip the collector loop. The peripheral speed of the second wheel is preferably greater than that of the first wheel so that the loop slips on its surface, collected material is scraped off the loop by scraper 18 comprising a lower block 18a having a dished channel therethrough to scrape the bottom of the loop and a leather strap 25a with a hanging weight 27 to scrape the upper part of the loop. A further scraper 28 is provided to remove any hydrophobic material which is deposited from the loop onto wheel 15. Rollers 30 are provided to hold the loop on the first wheel.

In this case the loop passes upwardly around the majority of the periphery of the second wheel before being diverted onto the teeth of the first wheel. The second wheel 1 is of greater diameter than the first wheel to provide the greater peripheral speed. Three scrapers 33, 34, 35 are provided to scrape that part of the loop between the second and first wheels, each scraping a different portion of the loop surface (Figs. 8-10 not shown) and the second of which 34 acts to direct the loop from the second wheel to the first wheel.
